How to reduce your bathroom water consumption and save money
Have you ever wondered how much water do you use during your daily bathroom activities?
It may actually come to a surprise to realize the high amount of water that we use for bathing and showering. So, even if our water bill may not be that high, it is worth to try to cut the amount of water we waste.
We call it to wasted water because we may be able to achieve the same results while using less water.
Let us show you what we are talking about and how you can reduce your bathroom water consumption and conserve water.
How to measure your bathroom water consumption
First you need to know how much water you are using and then you can decide if you are wasting water and where you can start saving water.
You need to start by finding out what the water flow of your water taps and shower head is. For that, you can just use a bucket and time how long does it take to get it filled to the one liter mark.
The time it takes to fill up the bucket to the one liter mark let’s you know how much the water flow is. For example, the tap delivers 1 liter of water every 5 seconds or the shower head delivers 9 liters per second.
For more information about how to measure the water flow rate, have a look to the video we have added below. Also, this site provides a very good overview and the difference between water flow and water pressure.
For measuring the toilet water usage, you will need to take the water meter readings before and after flushing the toilet. The readings will let you know how much water your toilet is using, for example, 10 liters per flush.
Again, for more information about how to read a water meter, have a look to the video we have added below.
And as example, in our case, this are our water flow rate results:
|Shower Head||1 liter every 5 seconds|
|Sink Tap||1 liter every 5,5 seconds|
|Toilet liquid waste||3 liters per flush|
|Toilet solid waste||7 liters per flush|
It is shocking to realize how much water it is being used in just a few seconds, specially while having a shower.
Know that we know how much water you are using per second or every time that you flush the toilet, the next step is to gather some additional information:
– For how long and how often are you taking showers. Does everyone at home spend the same time under the shower?
– An approximation on how many times the toilets are flushed per day.
– An estimation on how long you are using the water taps during the day.
And with all the information you have collected, you can already estimate your water usage and water cost.
In our case, for our household, this are our results:
|Total water usage||320||9600||115,200|
|Total water cost||0,7||21,2||253,4|
|Water usage estimation||Day||Month||Year||Total water cost|
|Toilet liquid waste||45||1350||16200||35,6|
|Toilet solid waste||18||540||6480||14,2|
|Water usage estimation||Time||Water usage|
|1 x quick shower||2,5 min||12 liters|
|1 x long shower||13 min||66 liters|
|1 x children bath||n/a||100 liters|
|1 x day of tap water||15 min||82 liters|
After estimating how much water and money we are spending and where we are spending it, we got to know that our water fixtures are using a considerable amount of water in just a few seconds.
With that information, we started checking if it was possible to (reasonably) reduce the water flow through a cost effective solution.

How to install a water flow reduction valve
After doing some research, we decided that installing an adjustable water flow valve it is an easy and economic way of reducing the amount of water we use while having showers.
With this valve we have managed to reduce the shower water flow from 1 liter every 5,5 seconds to 1 liter every 8,5 seconds without actually noticing any difference while having showers.
The advantage of the valve is that it is manually adjustable, so if some day we need to increase the water flow rate, we can do it without any effort.
Or, if our small children are just playing with the water while enjoying their shower, we can decrease the water flow down to 1 liter every 10 seconds without them noticing any difference.
Additionally, the valve is discrete and unless you know it is there it is barely noticeable.
For more details and specifications, clicking on the valve image below will direct you to the product in Amazon..
Reduce sink water wastage by reducing the water flow
Another solution that popped up by just having a closer look was that we could adjust the sink water flow rate by just adjusting the hot and cold water flow valves.
This way, we have adjusted the flow rate from 1 liter every 5 second to 1 liter every 9 second and even though the flow reduction it is noticeable, the truth is that the water flow was far to much and we were just wasting too much water.
1 liter of water every 9 seconds for cleaning hands, face or washing the teeth it is more than enough.
Reduce water consumption by installing a water saving tap aerator
Old faucet models run on average of around 15 liters of water per minute while a standard aerator can reduce the water usage to as little as 6 litters per minute.
Water saving tap aerators can reduce the water consumption even further and due to their low cost and easy installation are most definitely a water saving method to have in consideration.
We have installed a water saving tap aerator and the results speak by themselves
|Before (no tap aerator)||After (with and eco tap aerator)|
|1lites every 6 seconds||1 liter every 15 seconds|
|10 liters per minute||3,8 liters per minute|
|10 minutes per day = 100 liters||10 minutes per day = 38 liters|
|100 x 220 days per year = 33,000 liters||38 x 330 days per year = 12,540 liters|
|33,000 liters x 2 euro per cubic meter = 66 euro per year||12,540 liters x 2 euro per cubic meter = 25 euro per year|

Dual flushing toilets
The toilet flushing didn’t present any water saving opportunity for our particular case. Our house has a dual flushing toilet which is one of the most efficient solutions on the market.
Still, have in consideration that some very old toilet use considerable amounts of water, up to 15 liters per flush.
If this is your case and you are thinking about investing into installing a new toilet, just take some readings, crunch some numbers and the result may help into deciding if the saving are worth the investment.
